无法连接到MySQL /其他错误。 使用PHP
[英]Cannot Connect To MySQL / Other Error. Using PHP
问题描述
Trying to access a MySQL database on my machine. 
试图访问我的机器上的MySQL数据库。 It's on port 1338. 它在1338端口。
This is the PHP file: 这是PHP文件：
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<table>
<?php
$connection = mysql_connect("localhost:1338","root","password"); //connects to db
$selected = mysql_select_db("site_updatelog"); //selects the db to be used
//Check whether connection was successful
if(!$connection){
die('Could not connect to database: ' . mysql_error()); //Stop further execution of php script and show the error that occured
}
$sql = "SELECT comments, version, datetime FROM changeLog ORDER BY id DESC"; //form the query to be executed on the db
$result = mysql_query($sql, $connections) or die (mysql_error()); //execute the query, or die if there was an error
while($row = mysql_fetch_array($result)){
//Display the table of results
echo "<tr><td>". $row['version'] ."</td><td>". $row['comments'] ."</td><td>". $row['datetime'] ."</td></tr>";
}
mysql_close($connection);
?>
</table>
</body>
</html>
This is the output: 这是输出：
"; } mysql_close($connection); ?>
". $row['version'] ." ". $row['comments'] ." ". $row['datetime'] ."
Been messing around for quite a while and it still wont work. 已经搞乱了很长一段时间，它仍然无法正常工作。 Any ideas? 有任何想法吗？

使用mysql_query($sql, $connections)更改mysql_query($sql, $connections) mysql_query($sql, $connection)

可能是因为你的数据中有非转义字符，你正在回应 - 尝试将你的$ row ['comments']，$ row ['version']和$ row ['datetime']包装到htmlspecialschars

Using the code below only dies and reports error if (!$connection) 使用下面的代码只会死亡并报告错误if (!$connection)
$connection = mysql_connect("localhost:1338","root","password"); //connects to db
$selected = mysql_select_db("site_updatelog"); //selects the db to be used
//Check whether connection was successful
if(!$connection){
die('Could not connect to database: ' . mysql_error()); //Stop further execution of php script and show the error that occured
}
Try using 尝试使用
$connection = mysql_connect("localhost:1338","root","password"); //connects to db
//Check whether connection was successful
if(!$connection){
die('Could not connect to database: ' . mysql_error()); //Stop further execution of php script and show the error that occured
}
$selected = mysql_select_db("site_updatelog",$connection); //selects the db to be used
if (!$db_selected) {
die ("Can\'t use db : " . mysql_error());
}
$sql = "SELECT comments, version, datetime FROM changeLog ORDER BY id DESC"; //form the query to be executed on the db
$result = mysql_query($sql) ;
while($row = mysql_fetch_assoc($result)){
//Display the table of results
echo "<tr><td>". $row['version'] ."</td><td>". $row['comments'] ."</td><td>". $row['datetime'] ."</td></tr>";
}
mysql_close($connection);
This throws errors before running query. 这会在运行查询之前抛出错误。 Also changed mysql_fetch_array() to mysql_fetch_assoc() as mysql_fetch_array() requires 2 parameters mysql_fetch_array()更改为mysql_fetch_assoc()因为mysql_fetch_array()需要2个参数
